DSL and Cable Internet
Available now with Comcast ON DEMAND

DSL Overview

DSL was initially developed in 1989, and was designed to deliver high-speed capable of transmitting video over telephone lines. The connection consists of a DSL modem connected to your telephone jack, and uses a special frequency that allows you to use both your phone and internet at the same time.

Cable Internet Overview

Developed in the mid-90's, cable high-speed Internet uses your existing coaxial cable to send Internet data downstream. Cable Internet data generally travels the same channel (6 MHz) as your TV signal, and essentially takes up the same amount of space as your cable programming. Basically, your cable modem serves as the bridge between your cable company—the source of your Internet signal—and your home.

Advantages

• DSL - provides you with "always-on" Internet access without having to dial-up. You normally don't share bandwidth with other users, since your DSL is transmitted through a dedicated line—your own phone line. You may be able to use your existing phone line, requiring no additional installation. DSL is traditionally fast for both downloading and uploading, but the actual speed of your DSL Internet depends a lot on the provide, and the distance between your home and the central office.

• Cable Internet - No need to install additional lines, just the existing cable line that provides programming for your TV. The "always-on" connection works without interrupting your phone service, and location is rarely a problem with cable Internet. As long as your cable company offers high-speed Internet service, you should have several packages and prices to choose from. Speeds range can reach up to 20 Mbps, but since you are sharing bandwidth with other cable customer, speeds will vary depending on the number of people connected and the Internet provider you choose.

Equipment

• DSL - Uses both a copper telephone line with companies often offering a DSL modem with no additional charge. The DSL modem—unlike a typical dial-up modem that is installed inside the computer itself—is usually external and connects to a computer via a USB or Ethernet port. There is a possibility of added installation fees if an existing phone line is not available for connection, so check with the DSL provider to see if new wiring is necessary.

• Cable Internet - gives users high-speed Internet access through a cable TV network. Cable modems are generally available from cable companies for either a low monthly fee, or a one-time purchase, depending if there are contract terms.

Availability

• DSL - Generally, you have to be within a set distance from your provider to have access to DSL service. Again, DSL depends on whether your existing telephone lines can carry the signal, as not every line can or does. Contacting your telephone company and asking them to test your lines before signing up for DSL is a good idea.

• Cable Internet - Approximately 55 million cable customers are enjoying high-speed Internet, largely due to the fact that cable doesn't require any special wiring to use. If you have cable TV service—and your cable company offers Internet service in your area—then you have access to cable Internet as well.

Pricing

• DSL - If you have an existing phone line that can carry your DSL connection, then hassling with new wiring will save you money. Contracts often carry special offers, and modems and installation will also often be included depending on the contract terms. Installation fees for both cable and DSL are generally very similar.

• Cable Internet - Depending on how you bundle together your other services—phone and TV in particular—with your cable Internet, can greatly affect what you pay per month. Several cable companies will offer significant savings when you purchase either two or all three services in one package. The biggest difference in price— as both are close in range between $40-$50 per month—largely depends on where you live and the company you choose. Competition always drives prices.
